ᐅ Humidity has dropped dramatically

Hello everyone!

We have now been living in our new house for 14 months and are very satisfied. There is always a lot to do, both inside and outside. However, we have been concerned about the humidity levels in the house for some time.

We had a prefabricated timber frame house built, KFW 55 standard. We also use an air-to-water heat pump from Tecalor with a ventilation system that includes heat recovery. The humidity has dropped to below 20% during winter. As far as we know, the indoor humidity should be between 40% and 60%, partly for the sake of the mucous membranes and overall comfort. According to the technician, we cannot adjust anything further on the heat pump regarding this.

Is using a room humidifier our only option now, or does anyone have other suggestions?

Best regards,
SaRo

We ourselves are affected by the low humidity.

Our indoor humidity is quite low, and we notice it in our mucous membranes. However, we adapt to it seasonally. Better than a constant runny nose. I’m not sure if a humidifier is the right solution, but why not? You could try using a water fountain.

Low humidity is quite common in modern houses, but you might want to check if the airflow of the mechanical ventilation with heat recovery system can be reduced a bit. It’s also possible that you have a simple plate heat exchanger, which could be replaced with an enthalpy heat exchanger. That would make a significant difference.

Okay, this is a technical matter. I need to consult with an expert. Thanks 🙂

Below 20% is already quite bad.
